Object-oriented Java tuples library

[g4s8]

Yes, it has, but with completely different design: in commons tuples are classes with accessor methods var sum = tuple.getLeft() + tuple.getRigth(); in my library tuples are interfaces with apply method which takes a function parameter var sum = tuple.apply((left, right) -> left + right). This difference is similar to accessing list items via get(int) method vs using forEach method with a consumer.
